Monarch Airlines has collapsed into administration meaning all of its future bookings have been cancelled and leaving 11,000 customers overseas, the Civil Aviation Authority has said.

Monarch is the UK's fifth biggest airline and the country's largest ever to go into administration.

KPMG have been called in as administrators for both Monarch Airlines and Monarch Travel Group.

Travellers due to fly with Monarch have been told not to go to the airport.

The airline had been in last-ditch talks with the CAA over renewing its licence to sell package holidays but failed to reach a deal before Sunday's midnight deadline.

The Civil Aviation Authority says it has now been asked by the Government to charter more than 30 aircraft to bring passengers back to the UK.

Some 300,000 future bookings have been cancelled as a result of the company's failure and customers have been told to keep away from airports as there will be no more flights.

Customers - here's what to do

Customers affected by the company's collapse have been urged to check a dedicated website monarch.caa.co.uk for advice and information on flights back to the UK.

It also gives information to those passengers that have future bookings with Monarch but are yet to leave the UK.

The CAA said all Monarch customers who are abroad and due to return to the UK in the next two weeks will be flown home.

The flights will be at no extra cost to passengers and they do not need to cut short their stay, the regulator said.

The Government has warned passengers to expect disruption and delay as it works to ensure there are enough flights to return the "huge number" of passengers.

What has been said

CAA chief executive Andrew Haines said: "We know that Monarch's decision to stop trading will be very distressing for all of its customers and employees.

"This is the biggest UK airline ever to cease trading, so the Government has asked the CAA to support Monarch customers currently abroad to get back to the UK at the end of their holiday at no extra cost to them.

"We are putting together, at very short notice and for a period of two weeks, what is effectively one of the UK's largest airlines to manage this task.

"The scale and challenge of this operation means that some disruption is inevitable. We ask customers to bear with us as we work around the clock to bring everyone home."

Transport Secretary Chris Grayling said: "This is a hugely distressing situation for British holidaymakers abroad - and my first priority is to help them get back to the UK.

"That is why I have immediately ordered the country's biggest ever peacetime repatriation to fly about 110,000 passengers who could otherwise have been left stranded abroad.
